• Impinge Plate Belt Freezer

  
  (Custom solutions available based on product type and capacity.)

Three Core Systems

Insulation System

• Dual-side SUS304 stainless steel polyurethane sandwich panels.

• High-pressure injected PU foam with superior insulation performance.

• Double-seal doors with anti-freeze heating system to prevent ice buildup.

Drive System

• 304 stainless steel spring-wire conveyor belt (1.5 mm thickness, 10×20 mm pitch).

• Smooth surface, long lifespan, and low maintenance.

• Imported VFD (variable frequency drive) for stepless speed adjustment to match different product freezing times.

• Aluminum alloy evaporators with variable fin pitch for extended defrost cycles.

• Uniform air distribution via axial fans with waterproof, anti-moisture motors.

• Stainless steel air ducts and guide panels to ensure equal airflow across belt positions.

• 15% faster freezing than traditional tunnel freezers, reducing dehydration loss.

Heat Exchange System

Advantages vs. Traditional Freezers

• 15% shorter freezing time, saving energy and improving throughput.

• Low dehydration loss (<1.5%), preserving product quality and weight.

• Continuous operation, reducing downtime caused by frequent defrosting.

IQF Tunnul Freezer Applications

• Straight-line tunnel systems (mesh or impingement belts) for consistent freezing of diverse products:

  • Vegetables & Fruits: Peas, diced fruits, berries, cut corn

  • Meat & Seafood: Diced chicken, beef cubes, fish fillets, shrimp

  • Prepared Foods & Bakery: Pizza, cakes, mixed trays, frozen snacks

  • Surface‑freeze or crust requirements: For pizzas, burgers, flat seafood

Frequently asked questions

Q1. What is an IQF Tunnel Freezer?
A. An IQF tunnel freezer uses high-velocity cold air to freeze each product individually, preventing clumping and preserving taste, texture, and color better than traditional freezing methods.

Q3.How do I choose the right model?
A. Key factors include product type, packaging, required throughput (kg/h), inlet and core target temperatures, and freezing time. We provide custom configurations to match your production needs.

Q4. What is the typical freezing time?
A. Depending on product size and moisture content, freezing time is usually between 10–40 minutes, with adjustable belt speed and airflow control.

Q2. What products can be frozen?
A. It is suitable for seafood (shrimp, fish fillets), meat (poultry cuts, beef), fruits & vegetables (berries, peas, diced fruits), bakery items (pizza, cakes), and ready-to-eat meals.

Q5. Can it fit into my existing production line?
A. Yes, modular and space-saving layouts are available. We design systems according to your footprint (L × W × H) and utility constraints.

Q6. Do you provide complete design services for IQF production lines?
A. Yes. We offer turnkey IQF solutions covering raw material handling, processing, quick-freezing, and packaging. Our team also helps integrate all pre- and post-processing equipment, ensuring seamless setup, cost savings, and efficient operations.
